Adds a CANCELLED envelope status that privileged members (owner or team
admin/manager) can move a pending document into. Sending recipient
notifications via a background job while retaining the document in the
dashboard as proof of distribution.
Includes a dedicated Cancelled tab, single and bulk cancel actions,
the ENVELOPE_CANCELLED mutability guard, and e2e coverage for
permissions
and visibility.
This PR introduces bulk actions for documents, allowing users to select
multiple envelopes and perform actions such as moving or deleting 1 or
more documents simultaneously.
